Overview of Testing Requirements in Oregon

For All Medical Registrants and Retail Licensees

As of October 1, 2016, all marijuana items must be sampled and tested according to OAR 333-007-0300 to 333-007-0490 and OAR 333-064-0100 to 333-064-0110.

The Oregon Health Authority (OHA) is responsible for Cannabis testing rules that apply to both the medical and retail market. Any marijuana or marijuana product intended to be sold at a dispensary or retail shop must have been sampled and tested according to the testing rules.

Optional: A control study may be requested to reduce the number of samples that need to be taken for future testing once approval for a control study is received. Please review OAR 333-007-0440 for more information regarding how to perform a control study. Additional information for requesting approval for a control study can be found under Control Study Information.

If a processor or processing site does not have a certified
control study it must have the cannabinoid concentrate, extract or product
sampled in accordance with Exhibit B, Tables 5 and 6 (pdf) and the sample increments
prepared and analyzed separately.

Failed Test Guidance

The table and guidance below outline actions that must be taken when a Cannabis sample fails testing.

Failed test results must be reported to the overseeing state agency by the testing laboratory within 24 hours of completion of the laboratory's data review and approval procedures and be reported at the same time or before reporting to the grower or processor.

If the processing method can effectively sterilize the batch, it may either:

Be used to make a concentrate or extract; OR

The batch must be destroyed.*

If batch is made into a concentrate or extract, it must be tested for microbiological contaminants, solvents and pesticides.

Concentrate or extract

Batch may be further processed.

After further processing, batch must be retested for microbiological contaminants, solvents and pesticides.

If batch fails retesting, the batch must be destroyed.*

All other products

Must be destroyed.*

Solvent

Extract

Batch may be remediated.

A remediated batch must be retested for solvents and pesticides.

A batch that fails solvent testing that is not remediated, or if remediated fails testing, must be destroyed.*

Water activity or moisture

Usable marijuana

Batch may either:

Be used to make a concentrate or extract; OR

Undergo additional drying or curing and be resampled and retested.

Pesticides

Usable marijuana

Must be destroyed*; OR

If only the analytes piperonyl butoxide or pyrethrins are found and the Oregon Department of Agriculture determines that the pesticide products used were
listed on the Department’s Guide list for Pesticides and Cannabis and the product was applied in accordance with the label, the Authority or the Commission may permit the producer or grower to remediate the usable marijuana using procedures that would reduce the concentration of pesticides to less than the action level. A batch of usable marijuana that is permitted to be remediated must be re-sampled and re-tested for pesticides.**

Concentrate or extract

If all useable marijuana used to make the concentrate or extract passed pesticide testing, a process lot of concentrates or extracts that is permitted to be remediated must be re-sampled and re-tested for pesticides.**

Potency

All products

Product may be repackaged to meet concentration levels outlined in rule. A repackaged item must be resampled and retested

*Notification of product destruction

If a batch fails testing, it may not be destroyed without obtaining permission from the overseeing state agency.

A medical marijuana registrant that fails to comply with any of the testing rules will be subject to enforcements action which may include civil penalties or having their registration suspended or revoked.

After attempting remediation, the
batch or process lot must be re-sampled and re-tested for pesticides. If the batch or process lot fails for pesticides again then it must be destroyed as ordered by OMMP or OLCC. Remediation
of usable marijuana on failed pesticide tests is only available for batches that
only failed for exceeding action levels on piperonyl butoxide or pyrethrins.

Reanalysis and Retesting Guidance

Reanalysis

Growers and processors who request testing on a marijuana item and receive a failed result may request a reanalysis of the sample from the same laboratory within seven days of being notified of the failure.
